To tu whom it may concern.-

Beit knownthat I, JOHN O. STANLEY, acitizen of the United States of America, and a resident of Holyoke, in the county of Hampden and State of Massachusetts, have invented certain new and' useful Improvements in Ventilators, of which the following is a full, clear, and exact description.

This invention relates to ventilators, and more especially to that class thereof which are used for Ventilating large buildings; and it has for one of its objects the provision of a device of this character which may be assembled in a convenient manner and which, on the other hand, may be taken apart and packed in compact form ready for shipment.

My invention has, furthermore, for its object the provision of means whereby the several component elements of the ventilator may be assembled in such a manner as to render the Whole structure when huilt up a practically unitary device which possesses great strength and the parts of which willbe comparatively light in weight.

In the preferred form thereof shown my im-A proved ventilator comprisesa cylindrical shell or casing which is substantially cylindrical in form and which may be carried to any desired height, this casing being surmounted by a ventilator-cap comprising a deflector and a hood, both of which parts are held at some distance above the upper opening of said casing, as is common in devices of this character.

It should be stated at this time that it isl not the object of my present invention to construct a ventilator thev efficiency of which shall be in any Way greater than that of this class of ventilators in common use, since it is my special aim to construct a ventilator possessing the generic features of efficiency andy the hood-sections.

Inasmueh as the height of the ventilator above the roof of a building may be varied according to the general requirements, it should be understood that the `number of sections constituting the casing portion of my improved ventilator may be changed Without in any Way affecting the spirit of my invention. Likewise I wish to state at this time that it is immaterial what the number of the several sections of which the hood or the deflector are composed may be, since the principal object is to render the structure easy to erect or inanipulate when ready for shipment.

In the drawings, l0 denotes a roof, to which an annular plate 1l may be attached by any convenient means. This plate 11 has an upwardly-extending flange l2, the diameter of which is such as to lit into the lowermost section 13 on the ventilator-casing, (indicated in a Lgeneral Way by D.)

In Fig. 2 of the drawings the casing .D is shown comprising three sections 13 14 15, all

vof which are preferably cylindrical in form and, if desired, maybe made so as to telescope one into the other instead of being the same in size, as shown in this ligure. The sections 13 le l5 are preferably formed of sheetunetal stri ps the ends of which are overlapped and joined-as, forinstance, by screws or bolts (indicated at 16)-so that when required these bolts may be removed and each cylindrical section may be flattened out for Vpacking and shipment.` f

In order to render the casingD a rigid structure, I preferably interpose between said sections thereof annular members 17, shown herein substantially T-shaped in cross-section, and the cuter flange of which serves as a member against which any two adjacent sections may abut, as will be readily under- ICO stood, and the sections may be directly secured to said annular members in any suitable manner, if so desired.

Supported above the casing D and at a proper distance therefrom is a deflector V, mounted below but in contact with a hood H, the latter serving as a roof and protection against rain, rbc., entering the building.

Referring first to the hood I-I, it will be seen that the latter is composed of a plurality of sections 18, which are substantially triangular in shape and the sides of which are turned downward tov form flanges 19, adapted to enter hood-supports 20, which may be channeled to receive said flanges 19 and which are preferably tubular in cross-section and are provided in their upper surfaces with slots of sufficient width to receive the adjacent flanges of an adjacent pair of hood-sections, so that any water which may find its 'way between said flanges may be conducted away from the ventilator by passing along the tubular support 20, which may thus constitute a gutter. The supports 2O are preferably screw-threaded at their upper ends to enter correspondingly-formed apertures 21 in a crown member 22, disposed near and for supporting the upper ends of said hood-supports, this crown member being preferably unitary and of sufficient size to receive all of the hood-supports, which will thus extend vtherefrom radially. Near their lower ends the hood-supports 20 are preferably held in brackets 23, adapted to receive said supports and grooved at their upper sides to permit the flanges 19 of the hood-section to pass therethrough and into the support 20.

Means are provided for clamping the supports and the hood-sections firmly in place, these means comprising in the present instance bolts 24, (see Fig. 5,) which are screwthreaded in the brackets 23 and tend to contract said tubular hood-supports sufficiently to clamp the flanges entering said supports together.

Coperative with the hood l-I and held in contact therewith is a deflector V, formed in the shape of an inverted cone and also comprising a plurality of preferably triangular sections 25, having their bases 26 adjacent the hood-sections 18 and having their base corners cut away, as shown in 27, (see Fig. 7,) to fit around the hood-supports 20.

The deflectonsections 25 will rest with their corners against stop-faces 27, formed on the brackets 23, while their lower ends or apeXes are brought together and in contact with a deflector-support 28, consisting in the present instance of a rod attached to the crown member 22 and adjustably held therein-as, for instance, by nuts 29 and 30, respectively. The lower end of the rod 28 is screw-threaded to receive a nut 3l, whereby all the sections 25 are positioned relatively to the hood and lare forced upward andagainst the under side of said hood-sections 18, and, if desired, any suitable cap for retaining the sections 25 in contact with the rod 28 may be employed in addition to the nut 31. i

NVhile it has been clearly described in what manner the hood-sections 18 are held near their lower ends in the supports 20, means are provided for maintaining also the Lipper ends of said sections in proper positionand in contact with said supports, these means comprising in the present instance a cap or guard 32, preferably conical in section and surmounting all of the hood-sections and the crown member and centralized relatively to the'deflector-support 28, and consequently to the crown member 22-as, for instance, by a nut 33 in screw-threaded engagement with the rod 28-thus constituting a finial for the ventilator.

In order to retain the deflector at properl distance from the mouth or top of the casing, l preferably employ a series ot' posts 34 in screw-threaded engagement with the brackets 23 above mentioned and having base members 35 grooved at their under side, as shown in 36, to fit over the top edge of the uppermost section 15 of the ventilator-dome D, this edge being preferably reinforced by a band 37, riveted or otherwise secured to said section 15. Each of the base members 35 may be provided with an ear 38 for receiving a bolt 39, whereby not only said base members are held on the member adjacent 15, but whereby, furthermore, all the casing-sections may be drawn together to form a rigid structure even if the individual sections are not bolted or otherwise secured to the annular members 17, above mentioned.

The manner of securing the bolts 39 may be varied, the construction shown in Fig. 2

of the drawings illustrating said bolts secured,

directly to the roof of the building, and it should of course be understood that said bolts may be secured at their lower ends to the plate 11 without in any way departing from the spirit of my invention.

The operation of assembling the several components of my improved ventilator is extremely simple and is as follows: It being supposed that the plate 11 is in position and firmly fastened to the roof 10, the dome-section 13 is first placed in position, whereupon the first annulaimember 17, the section 14, the second interposed member 17, and the section 15 are successively superposed in the order named. The hood-supports 2O are as- IOO IIO

sembled with the crown member 22, and the guard 32 is now placed over the rod 28 and the nut 33 `turned to force saidguard 32 outward until the plates 18 are rmly in contact with the supports 2O at their outer ends. The deflector-sections 1n ay new be put into place and the nut 3l turned until all of the Sections 25 are fixed in position, and finally the bolts 39 will serve to iirmly attach the entire structure to the roof l0.

It is of course obvious that the method liust described of assembling the various par-ts may be modilied according to the judgment of those in charge of'erecting the structure. Likewise it will be understood that the ventilator after it has once been fitted in the shop may be readily taken apart and packed forshipment, the several sections ofthe hood, as well as those of the defl'ector,` being preferably substantially alike, and thus capable of being packed in small spaces.

In Fig. S the bracket is shown with a ker 23 below the opening for the tubular hoodsection support, the screw-bolt. 24: contracting the upper part of the bracket to constrict it and the tube 2O for clamping the flanged hood-sections. t
